The ehci-hcd and other usb modules are not preloaded from initramfs generated by the genkernel command. This fault is caused by a missing character in the modprobe script.
Created attachment 193915 [details, diff] Patch for /usr/share/genkernel/generic/modprobe Adds 2 changes - 1. modifies error message on module load failure to display the name of a dependent module and 2. fixes incorrect grep command which is confused by the presence of both usbcore.ko and wusbcore.ko in the modules.dep file

Kernel 2.6.29-r5 genkernel 3.4.10-r2
Created attachment 193974 [details, diff] Add capability to customise initramfs This patch modifies the genkernel script to read an additional file 'my_modules_load' that can override the setting in the file 'modules_load'. This can be used to tailor the initramfs file to a specific computer.
Created attachment 193975 [details, diff] Add capability to customise initramfs - 3.4.10.904 Modifies genkernel script to read an additional file 'my_modules_load' after 'modules_load' in order to customise initramfs
Created attachment 193979 [details, diff] Add SD category for scsi emulation Adds SD class of module that contains the SCSI emulation code needed for PATA/SATA/USB/FIREWIRE disks
Created attachment 193980 [details, diff] Add ext4,squashfs,aufs filesystems. Add SD class of modules This patch works in tandem with the initrd.defaults patch
Created attachment 193982 [details] Script to generate tailored my_modules_load file that customises initramfs This script will generate a 'my_modules_load' file that can be used by the patched genkernel to create an initramfs that is tailored for the current PC. It uses the pcimodules command from pciutils.
I've applied the patch for modprobe, which is what this bug was originally about. However, I'm not sure what the extra -n bit is about. What's this for? You'll need to file separate bug(s) for the other stuff.

This made booting the kernel quite slow and consumed unnecessary memory. I had a product that installed on a wide variety of motherboards and it was inefficient to compile the kernel for each motherboard separately. So the idea is to compile one generic kernel with everything as a module and then modify the initramfs to only load the necessary modules. Loading the necessary modules is defined by an additional file 'my_modules_load' which overrides the file 'modules_load' if it exists (genkernel.diff) The PATA,SATA classes also require the sd_* modules so these modules are separated into their own class SD. Additionally I added some extra filesystems to the FS class (initrd.defaults.diff, modules_load.diff). Lastly I wrote a script (my_modules) which can automatically generate the 'my_modules_load' file - subsequently rebuilding the initramfs with the 'genkernel initrd' command results in faster booting and a smaller initramfs without any need to do a lengthy kernel recompile. I have been using this scheme successfully for over a year now. The my_modules script is a bit clumsy and could do with some work. It would probably be better as an additional option to genkernel. I will submit these as separate 'bugs' if you want - however the present genkernel works well enough so these fixes are not bugfixes but more of an improvement.
Looks like a duplicate of the code I submitted in bug 186652 for loading a customized set of modules.
PS: Adding keyword "Inclusion" and "[patch] " prefix to better show this bug's nature in searches...
